Chelsea have been left sweating over the fitness of
Frank Lampard for the weekend showdown with Manchester United, after the midfielder limped out of last night’s defeat to Shakhtar Donetsk.

Lampard, 34, came off after just 15 minutes of the 2-1 loss in Ukraine with a recurrence of the calf injury that ruled him out of England’s World Cup qualifiers against San Marino and Poland.The midfielder will now undergo a scan today to determine the extent of the problem, with the results expected on Thursday.Should the issue be serious, Lampard could miss the top of the table clash on Sunday against United, and leave the Blues boss with a real headache in the centre of midfield.Di Matteo said: ‘It’s basically a recurrence of an old injury.‘He was training with us fine and there were no alarm bells before the game. He was in good condition to play.’Jon Obi Mikel, Ramires and Oriol Romeu are Di Matteo’s only other recognised options to deputise for the England international, who would have captained the side in the absence of the suspended John Terry.
